I'm thinking about getting rid of my Oscar, upgrading, and add some severums, a Lima shovelnose, possible a ghost knife, and maybe a few cichlids, anything that would harass him there?
the cichlids depending on the type, and the other 2 (depending on personality) may bother him if they are bigger. I'm sorry I should have been more clear when I asked about top cover, I meant are there floating plants or do you keep the lights off for some of the day? Gar prefer tanks with top cover such as plants or even a darkened lid or dim lights. They spook easily, mine for no reason dart across the tank.
